Patented pr. 28, 1931 r rsics ELMER F. HENNENKAROF' UINCINNT, OHIO, ASSIGNOR,`BY TEESNE ASSIGNMENTS, TO THE OHIO-PATTE-RCN 'SNOB-KS ANDEOUNDRY COMPANY, OF CINCINNATIE, OHIO,

A CORPORATON' 'OF OHIO VALV `Application filed February 4, 1929. Serial 1\To.`337,398.

This invention relates to an improved valve of the packless Jvariety used in steam, hot Water `and Yvapor circulating systems,f but eqi, .tllypuseful as a water faucet and in other "i relations -where it is desired'tocontrol the fluid whether in liquid or gaseous form.

One feature of the invention is predicated upon 'the vfact that the valve opens or closes with but one, turn or single rotation of the handle, the arrangement being such that in spite of this slight turn of the handle, there is'inevertheless -a relativelygreat degree of movement ofthe valve toward and from its Seat.

'lt is also-a 4featureto provide 'a valve with a casing` ofthe angle type having its intake offset with respect to the, valve sean-thereby permitting the provision of, a valve casing of 'standard size having a relatively large valve lseat opening. n

vIt is a further object-'to provide a valve of thistype which is characterized bya novel internal carrierA having both rotary and reciprocatorymotion and designed tofpermit the *J valveper se to beswivelly mounted thereon, whereby to insurean effective closing of the valve against itsseat to Vcompensatefor unequal expansionfandY contraction.

One ofthe chief structural features of merit is` an especially' desigi'ied non-binding bonnet assembly made up of separable parts to facilitate repair and adjustment, and distinguished by a novel packing box and gland and associated valve operating shaft.

Other features and advantages will become more readily apparent from the following description and drawing.

Tn the drawings Figure 1 is a view in section and elevation of a complete packless valve constructed in accordance with the present invention.

Figure 2 is a central vertical sectional view of the same showing the exacting relationship of parts.

Figure 3 is a horizontal sectional view taken approximately upon the pla-ne of the line 3 3 of Figure 1.

Figure 4 is a similar horizontal sectional view taken on the plane of the line 4-4 of Figure 2.

CrD

Referring'now to the drawings byreferf encefnumerals it will vbe observed that 5 designates the globe-like casing constructed 'to pro-vide a comparatively large size Vwaterway and internal valve chamber 6. The reference character 7- designates a pipe connection having an of-set valve seat 8 associated therewith. Extending at right angles to this-is a pipe connection 9, anda union or coupling 10 carryingv an associated vcoupling nipple'll. Also formed integrally with this casing is an especially designed neck 12 having small external screw/'threads to couple it with or to accommodate the bonnet assembly 13 and having relatively largescrew threads 14 to accommodate a valve carrier 15. This valve carrier isin the form of a cup having a rim at its top provided v with screw threads as at 16 meshing with the Vthreads 14. As shown in Figure 1 this carrieris formed on diametrically opposite sides withnotches or slots 17 yfunctioning as keyways. L This carrier is intendedto be rotated and Vto be moved toward and from the valve,

12. 'This cap is provided at its center with `a stuiiing boXland packing glandfor the operating'slraft 19; This `stufifing box structure includes avdepending annulus 20 telescoping down into the cup-like carrier 15 and 4an upstanding annulus'21 functioning as a collar. vSuperposed packing rings 22 and 23 Vare seated in the lower annulus 20. A dust cap 24 fits telescopically over the upper collarforming annulus and a coil spring 25'is fitted within the dust cap and collar, bearing at its opposite ends on iiberrings as shown. c This packing boX and packing gland structure-provides an effective iuid-tight mounting" and joint around the operating shaft 19. This shaft .is provided r'with an operating handle orknob 26-onfitstop and linst below thehandle is an outstandingy collar 27-and a groove accommmiatingy a. horse-shoe retainer 28. Incidentally, it will be no-ted that the central portion ofthe dust cap 24 is provided with a depression to accommodate the retainer. This serves to maintain the dust cap in assembled position and retains the spring 25 under compression. On the lower end of the shaft is a disk 29 having diametrically opposite lugs 30 functioning as keys and extendingl into the key-ways 17. This provides an operating connection between the shaft and the valve carrier. With this arrangement it is obvious that when the knob 25 is grasped and rotated, this will turn the operating shaft 19 as well as the disk 29 on the lower end thereof. The slidable key connection between this disk and the carrier will turn the carrier. Hence, when the Vshaft is turned in one direction, the carrier andthe valvel will move toward the valve seat, and when turned in the opposite direction it will move away from the valve seat. The threads on the carrier and casing are such that a single revolution of the knob will serve to seat the valve, if the valve is open, or will serveto Vmove the valve to the open position shown in Figure 2 when turned in the opposite direction. Thus a rapid closing and opening of the valve is effected by a single turn of the kno-b. i

In connection with a centralized packing gland it will be observed that the expansion of the coiled spring exerts an upward thrust on-the dust collar 24: and a downward compression on the packing rings 22 and 23, Also it exerts an upward lift on the operati ing shaft 19 and serves to bind this shaft tightly against a yliber packing ring 31 which is interposed between the.v disk and the bottom of the packing boxannulus 20. It may be mentioned that the annulus as well as the disk is formed with a circumferentialrib, the ribs fitting into circumferentially extending grooves in the packing ring to eect a 'tight joint connection.

rThe following are some of the features of merit. rllhe valve includes a positive grip, composition knob'or handle of heat-resisting material, a non-binding-bonnet assembly, a special tempered spring which is cadmium plated and non-corrosive. In addition, there is a special molded permanent packing ring and brass washer arrangement, as well as a heavy disk carrier with wide diameter threads. Then too, there is a disk with a two-lug or two-rib contact with two slots in the disk carrier and a stem or shaft and driving disk cast in one piece which is positively non-rising. Further I call attention tothe swivel disk holder, the exceptional high lift, the comparatively large size waterway, and other features already'mentioned.

'A careful consideration of the description in connection with the drawings will enable the reader to obtain a clear understanding-of the same. Therefore a more lengthy description is regarded unnecessary.

Minor changes in shape, size and rearrangement of details coming within the eld of inventionclaimed, may be resorted to in actual vpractice if desired.

I claim:

1. Ina valve of the class described, a casing having inta-ke and discharge pipe connections, an internal valve chamber, a valve seat in said chamber, and a bonnet coupling neck opposite the valve seat, said neck being internally screw threaded, a valve carrier in said chamber threadedly connected with the internal screw threads of said neck, a valve mounted on said carrier and movable toward and from said seat, a'bonnet assembly attached to said neck and including a rotary operating shaft having operating connection with said carrier, said carrier being of cupped form andvv provided with diametrically opposite key-ways, and said shaft having a disk fitting in said carrier and said disk having outstanding keys fitting in said key-ways.

2. In a valve structure of the class described, a casing having an internal valve seat, a valve chamber, and a neck, said neck being internally and externally screw threaded, a substantially cup-shaped carrier having a threaded rim portion connected with the internal threads of said neck, a valve swivelly mounted on said carrier and mov able toward and from said seat, a bonnet assembly including a cap having a screw threaded rim attached to the external threads of said neck and a central packing box and gland, a shaft extending through said packing box and gland, having an operating knob on its outer end, and a disk on its inner'end tting into said cup carrier, said carrier having vertical diametrically opposite key-ways andsaiddisk having diametrically opposite keys extending into said key-ways.

In testimony whereof I aiix my signature.
